Two months after he was discharged from the hospital after a grueling fight with Ebola, Dr. Ian Crozier was back in the hospital with searing eye pain. When doctors looked closer, they were astounded to find cells of the virus still lingering inside his eye. His case we detailed in a report published yesterday in the New York Times.

The reason may be due to the fact that these areas are considered “immune privileged,” meaning they are mostly separated from the immune system. Separation from the immune system can be beneficial for the eyes and testicles, because the same molecules that fight off pathogens can actually damage these sensitive areas. However, this potentially makes them ideal places for viruses to linger.
